The assembly of six genes that encode enzymes from glutamate-fermenting bacteria converted Escherichia coli into a glutaconate producer when grown anaerobically on a complex medium. The new anaerobic pathway starts with 2-oxoglutarate from general metabolism and proceeds via (R)-2-hydroxyglutarate, (R)-2-hydroxyglutaryl-coenzyme A (CoA), and (E)-glutaconyl-CoA to yield 2.7 ± 0.2 mM (E)-glutaconate in the medium.
